JEFFERSON M. GARDNER, OF NEW LONDON, CONNECTICUT.

CONDENSER FOR COTTON FIBERS.

SPECIFICATION forming part of Letters Patent No. 709,090, datedSeptember 16, 1902.-

Application filed January 5, 1899. Serial No. 701,256. (N0 model.)

To all whom it may concern:

Be it known that I,JEFFERSON M. GARDNER, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented certain new and useful Improvements inCondensers for Cotton Fibers; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art towhich it appertains to make and usethe same.

The object is in a simple and efficient manner to separate thelint-cotton from the current of outgoing air produced by the rapidrotation of the gin-brush in the process of removing the lint-cottonfrom the saws and to condense this lint into a smooth and even bat;furthermore, to permit rapid andeasy escape of the air from the machine,thereby to afiord the gin-stand the greatest freedom of action inremoving the lint-cotton from the seed.

The invention consists in the novel construction and combination ofparts of a cotton-batting condenser, as'will be hereinafter fullydescribed and claimed.

In the accompanying drawings, forming a part of the specification, andin which like letters of reference indicate corresponding parts, I haveillustrated one form of embodiment of my invention, it being understoodthat other forms of embodiment thereof may be employed without departingfrom the spirit of the same, and in the drawings Figure 1 is a view inlongitudinal vertical section of a machine embodying my invention. Fig.2 isaviewin front elevation showing more particularly thebatting-rollers, and Fig. 3 is a view in end elevation showing themechanism for driving the condenser-cylinders and the batting-rollers.Fig. 4; is a detail end view of the batting-rollers.

Referring to the drawings, A designates an air and cotton flue, which issuitably connected to the condenser-frame A as shown in Fig. 1. In. theprocess of ginning lintcotton from the seed lint-cotton is blown by acurrent of air produced by the rapid rotation of the gin-brush (notshown herein) though the flue A and against the condensercylinders A andA. These cylinders maybe constructed of any suitable material adaptedfor the purpose, preferably, in this instance, of wire-gauze suitablysecured to internal heads or spiders a. The cylinders are run atdifferent rates of speed, the lower cylinder A 'being driven at a rateof speed about onefourth as fast as the upper cylinder A By this meansthe lint-cotton is thrown from the upper cylinder A onto the lowercylinder A and the air is allowed to escape through the meshes of thewire covering of the two cylinders and freely passes out at each endthereof and through fines A provided at each end of the frame A for theescape of air, as shown in Fig. 2. The two cylinders are set at asufficient distance apart to permit the lint-cotton to pass between themin such quantity as may be desired.

Arranged in front of the cylinder A are the batting-rollers A A Theroller A is provided with rubber or leather flaps and is rotated inthe-same direction as the wire cylinder A to prevent any lint-cottonbeing carried below the discharge-opening by the cylinder A The upperbatting-roller A is by preference covered with wire-cloth and subservesthe double function of pressing the lint-cotton into an even smooth batand discharging the same and of permitting the escape of sufficient airto insure the cotton being freed from the cylinder A by the air pass ingthrough this cylinder and out through the roller A.

It is to be understood that, if desired, the cylinders and rollers maybe made adjustable with relation to each other, so as to vary thethickness of thebat.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a condenser for cotton fiber, the combination withcondensing-cylinders, of batting-rollers arranged adjacent thereto,adapted to receive and, by pressure, compact the cotton into a bat oneof the batting-rollers being provided with means adapted to direct thecotton from the condensing-cylinders into engagement with thebatting-rollers and the other having a surface pervious to air,substantially as described.

2. In a condenser for cotton fiber, the combination withcondensing-cylinders, of batting-rollers arranged adjacent theretoadapted to receive and,-by pressure, compact the cotton into a bat, oneof the batting-rollers having a surface pervious to the passage of air,substantially as described.

3. In a condenser for cotton fiber, the combination withcondensing-cylinders, of bat ting-rollers adapted to receive the cottonfrom the condensing-cylinders and, by pressure, compact the same into abat, one of the batting-rollers being provided with flaps or projectionsand the other having a surface pervious to air, as and for the purposespecified.

4. In a batting-condenser, the combination of two wire-gauze-coveredcylinders arranged approximately one above the other, means for drivingone cylinder at a higher surface speed than the other, batting-rollersarranged adjacent thereto adapted to receive and, by pressure, compactthe cotton into a bat and the surface of one of the batting-rollersbeing covered with wire-cloth, substantially as described.

5. In a condenser for cotton fiber, the combination of twocondenser-cylinders, one of which is perforated to permit escape of air,the two cylinders revolving in opposite directions and having differentsurface speeds, batting-rollers adjacent to one of thecondenser-cylinders and the upper roller being covered with wire-cloth,substantially as described.

6. In a condenser for cotton fiber, the combination of twocondenser-cylinders, one of which is perforated to permit escape of air,the two cylinders revolving in opposite directions and having differentsurface speeds, means for feeding the cotton fiber, under pressure, tothe condenser-cylinders, and two batting-rollers arranged adjacent tothe condenser-cylinders in position to receive the condensed cotton fromthe condenser-cylinders, one of the rollers having a surface pervious toair, substantially as described.

7. In a batting-condenser, the combination of two gauze-coveredcondenser-cylinders arranged approximately one above the other,

means for driving the upper cylinder at a higher surface speed than thelower cylinder, and two batting-rollers arranged adjacent to the lowercondenser-cylinder, the lower batting-roller being rotated in the samedirection to that of the said lower cylinder, and the upper rollerhaving a surface pervious to air, substantially as described.

8. In a cotton-batting condenser, the combination of gauze-coveredcondenser-cylinders arranged approximately one above the other, meansfor driving the upper cylinder to impart thereto a higher rate ofsurface speed than that of the lower cylinder, batting-rollers arrangedadjacent to the lower cylinder, the lower batting-roller being roratedin the same direction as the lower condenser-cylinder and provided withflaps or projections, and the upper roller being covered withwire-cloth, a housed dischargeflue arranged above the lower cylinder,and means for causing the proper separation and collection of thelint-cotton and condensation of the same into a smooth and even bat,substantially as described.

9. In a batting-condenser, the combination of two wire-gauze-coveredcylinders arranged approximately one above the other, means for drivingthe upper cylinder at a higher rate of surface speed than the lowercylinder, batting-rollers arranged adjacent to the lower cylinder, thelower roller being rotated in the same direction as the lower cylinder,and the upper roller being covered with wire-cloth, a houseddischarge-flue arranged above the lower cylinder, and means for causinga proper separation and collection of the lintcotton and condensation ofthe same into a smooth and even bat, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
